That is not good. You will need to compare the patch code and the
existing kernel code. Maybe parts of your preempt patch code is
already
in the Fedora kernel source.
Hmmm. I found this link:
http://rpmfind.rediris.es/rpm2html/fc2-i386-updates/kernel-doc-2.6.8-1.52...
that says that the voluntary preemption patch has already been added
but the instructions to enable voluntary preemption from
http://wiki.philkern.de/5.html
echo 3 > /proc/sys/kernel/voluntary-preemption
fail because the file doesn't exist. So I'm not sure whether it has or
hasn't or perhaps there a step missing.
Steve.
